Your beef is with the Regulator and what they expect of the trainees for licence issue.
As you say you learn on the job, as you did. It is merely the starting point for further learning.
You don’t expect a newly qualified doctor after 5/6 years of medical school to have the theoretical knowledge of a hospital consultant. Nor should you expect a new (f)ATPL pilot have the experience of a TRE?
Nurture them, not slag them off.
